B. Algorithm to compare two numbers.
Step 1: Start.
Step 2: Read two numbers and store them in A and B.
Step 3: Compare the numbers A and B.
Step 4: If A is less than B, print "A is smaller" and go to Step 7.
Prime (Ver. 2.2)-VI Step 6: If A is equal to B, print "A and B are equal".
Step 5: If B is less than A, print "B is smaller" and go to Step 7.
Step 7: Stop.
Defining Flowcharts
A flowchart is a type of graphical diagram that represents an algorithm. It is a set of
instructions that can be followed to perform a specific task, workflow, or process. This
116 diagrammatic representation illustrates a solution model for a given problem. Flowcharts
are used in analysing, designing, documenting, or managing processes or programs in various
fields.
Flowcharts show the sequence of instructions in a program. They play a vital role in
programming by helping to understand the logic of complicated and lengthy problems.
Once a flowchart is drawn, it becomes easy to write the program in any high-level
language. Flowcharts are also helpful in explaining the program to others. Thus, it is
accurate to say that a flowchart is essential for a better understanding of a complex
program.
Symbols used in Flowcharts
Different symbols are used to draw different types of flowcharts. Let us discuss them.
Name Symbol Description
It indicates the start and stop points of the flowchart.
(Start/Stop)
It usually contains the words 'Start' or 'Stop'.
It shows a process or action step. This is the most
Process
common symbol used in flowcharts.
It indicates a question or branch in the process flow. It
Decision
is used when there are 2 options (Yes/No).
It represents material or information entering or leaving
Input/Output
the system, i.e., input and output.
